Description

Technical Field

[0001] The present invention belongs to the field of textile machinery, and particularly relates to a double-supporting claw pushing cam disc device for a ring spinning frame. Background Art

[0002] The existing collective doffing system equipped on a ring spinning frame involves a cam disc conveying method, including two types: "pushing the cam disc by a cylinder" and "driving the cam disc by a steel belt". Among them, the technology of pushing the cam disc by a cylinder is the most mature and widely used. In the way of pushing the cam disc by a cylinder, a cylinder rod is directly connected to a support bar through a connecting plate, and the support bar is connected to a supporting claw. A forward stroke is generated when the cylinder rod extends out of the cylinder, and a return stroke is generated when the cylinder rod retracts into the cylinder, driving the supporting claw to intermittently push the cam disc forward. However, in this motion transmission method, whether using the forward stroke or the return stroke of the cylinder rod to drive the supporting claw forward, always one of the operating strokes will be wasted: if using the forward stroke to push the cam disc, the return stroke will be wasted; if using the return stroke to push the cam disc, the forward stroke will be wasted. During the whole operation process, the cylinder only does effective work for about 1 / 2 of the time. In this way, the adverse result is that when the ring spinning frame spins low count yarns, since the spinning time is very short and the spinning process has been completed, but the cam discs in the collective doffing system have not been conveyed completely yet, or the ring spinning frame is an extra-long spindle number ring spinning frame with a large number of spindles. When the spinning process of the ring spinning frame is completed, due to the large number of spindles and the excessive number of cam discs, the collective doffing system has not finished conveying the cam discs yet. This makes the mainframe of the ring spinning frame have to stop working to wait for the collective doffing system to complete the cam disc conveying. Such waiting greatly reduces the continuity of production, greatly reduces the use efficiency of the mainframe, wastes time, and also severely restricts the application of the extra-large spindle number ring spinning frame in production practice.

[0015] As Figures 1-5As shown in the figure, a double-supporting-claw pushing convex disk device for a ring spinning frame includes a base 1, a cylinder 2, a thrust frame 3, a first rack 4, a second rack 10, a first sliding linear guide rail 5, a second sliding linear guide rail 11, a first connecting plate 6, a second connecting plate 12, a first support bar 7, a second support bar 13, a first supporting claw 8, a second supporting claw 14 and a gear assembly 9. The cylinder 2 is fixedly arranged on the base 1 through screws and washers. The end of the cylinder rod and one end of the thrust frame 3 are fixedly connected through nuts. When the cylinder rod moves back and forth, the thrust frame 3 moves synchronously with the cylinder rod. The other end of the thrust frame 3 is fixedly connected with the first rack 4 through screws. The first sliding linear guide rail 5 and the second sliding linear guide rail 11 are fixedly arranged on the base 1, and a slide table 24 that can move axially is arranged on the first sliding linear guide rail 5 and the second sliding linear guide rail 11. The slide table 24 is fixedly connected with the first rack 4 and the second rack 10 through screws. The first rack 4 can perform axial movement on the first sliding linear guide rail 5 through the slide table 24. Similarly, the second rack 10 can also perform axial movement on the second sliding linear guide rail 11. The first connecting plate 6 is fixedly connected with the first rack 4 through screws. The second connecting plate 12 is connected with the second rack 10 through screws, and the movement of the rack can drive the connecting plate to move synchronously. The first support bar 7 and the second support bar 13 are arranged below the convex disk guide rail 19. The other end of the first connecting plate 6 is fixedly connected with the first support bar 7. The other end of the second connecting plate 12 is fixedly connected with the second support bar 13, and the connecting plate can drive the support bar to move synchronously. The first supporting claw 8 is arranged on the first support bar 7 through a supporting claw support shaft 15 and a shaft retaining ring 16. Similarly, the second supporting claw 14 is arranged on the second support bar 13. The first supporting claw 8 and the second supporting claw 14 are mirror parts, which are installed on one of the support bars and can also cross over the other support bar, so as to realize that the two contact points of the convex disk are symmetrical about the central plane in the advancing direction, thereby realizing the pushing of the convex disk without lateral force. The gear assembly 9 is composed of a gear 20, a gear shaft 21, a rolling bearing 22 and a hole retaining ring 23. The gear 20 in the gear assembly 9 is arranged between the first rack 4 and the second rack 10 and meshes with the first rack 4 and the second rack 10.

[0016] A fixed dust-proof cover 17 is also fixedly arranged on the base 1. The fixed dust-proof cover 17 wraps the gear and rack structure. A movable dust-proof cover 18 is fixedly arranged on the rack and moves with the movement of the rack, and cooperates with the fixed dust-proof cover 17 to completely wrap the gear and rack structure without gaps. The cylinder 2 can also be equivalently replaced by a servo motor or a walking motor.

[0017] When the cylinder rod moves back and forth, the thrust frame 3 moves synchronously with the cylinder rod. The other end of the thrust frame 3 and the first rack 4 are fixedly connected together by screws and washers. Therefore, the first rack 4 and the thrust frame 3 move synchronously. The first rack 4 and the second rack 10 are respectively arranged on both sides of the gear 20 in the gear assembly 9. When the first rack 4 moves forward along the first sliding linear guide 5, the gear 20 rotates in one direction, driving the second rack 10 to move backward along the second sliding linear guide 11. Similarly, when the first rack 4 moves backward along the first sliding linear guide 5, the gear 20 moves in the opposite direction, driving the second rack 10 to move forward along the second sliding linear guide 11.

[0018] Since the first connecting plate 6 is fixedly connected to the first rack 4, the movement of the first rack 4 can drive the first connecting plate 6 to move synchronously. The other end of the first connecting plate 6 is fixedly connected to the first support bar 7, thereby driving the first support bar 7 to move, and the first support claw 8 arranged on the first support bar 7 to move synchronously. Similarly, the movement of the second rack 10 drives the second connecting plate 12, the second support bar 13, and the second support claw 14 to move synchronously. Therefore, whether the cylinder rod is in the forward stroke or the return stroke, there will always be a set of support claws pushing the cam forward.

[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
